Specification of Letters Patent.

Patented July 13, 1915..

Application filed May 22, 1913. Serial No. 769,205.

To all whom it may concern: Be it known that I, PHILIP SCI-IWIOKART, a citizen of the United States, and a resident of the city of New York,borough of Brook lyn, in the county of' Kings and State of New York, have invented a newand Improved Ventilating and Lighting Construoe tion, of which the following is a full, clear, and exact description.

The invention. relates to walls, skylights, sidewalks, floors, roofs and other parts of buildings. and other structures, and its, object is to providea new andimprovedventilating and lighting construction arranged to provide an exceedingly strong and durable structure,and to permit of quickly and accurately assembling the various parts without the employmentofxskilled' labor.

In order to producethe desired result, use is made of side beams having spaced seats, cross bars in the form'of; angle irons fitting the said seats with the corners downward and the side membersdiverging upwardly, and building light units having theirsides seated on the edges of theside members of the cross bars.

A practical embodiment of the invention is represented in [the accompanying drawings forming a part of this specification, in which similar characters of'referenceindicate corresponding parts in all the views.

Figure l is a plan view of the ventilating and lighting construction with portions of the cementitious filling and some of the reinforcing rods omitted; Fig.2 is a sectional side elevation of the same on the line 22 of Fig. 1; Fig. 3 is a reduced plan view of the skeleton frame for supporting the units, the reinforcing and and the cementitious filling; Fig. 4 is an enlargedcross section of the same on the line H of Fig. 1 ;Fig. 5 is an enlarged sectional side elevation of a modified form of a unit; Figs. 6, 7 and 8 are side elevations of. different forms of the supporting side. beams of the skeleton frame; and Fig. 9-, is a perspective view-of a modified form of the supporting frame for the units. 1

The units A are supported on spaced cross bars B'of a skeleton? frame. (see Fig. 3), having side beams C supporting the said cross bars B and resti'ngon a suitable foundation. The cross bars Band the side beams C are preferably made of angle irons and the. side beams C have their vertical members provided with, triangularly shaped seats G in which are seated the cross bars Bhaving their corners downward and the side members diverging in an upward direction, as Will be readily understood by reference to Fig. 2. Each of the units A consists ,of an open frame A, preferably 'square', and having the lower edges of its ,A and fitting onto the corresponding side members of the cross bars B so as to prevent sidew se shifting of a unit on 1ts two sup- "porting cross bars B. The ends A of the frame A ofa unit are inclined upwardly and inwardly, as plainly indicated in Fig. 4, and are provided with base flanges A,

-A, ofwhich the base flange A of one frame A abuts against the flange A of the next following unit supported on the same cross bars B. The base flange A of each unit is provided with a dovetail tongue A fitting into a correspondingly shaped groove A inthe abutting base flange A of the next following unit, as plainly indicated in Fig. 1 so that the several unitsarranged in one row and supported by the same pair of cross bars B are connected with each other. A strengthening rib A connects integrally with the tongue A the base flange A and the corresponding end A so as to give the desired strength to the tongue A and the rib A is provided with a top notch A forming a seat for thereinforcing rod D extendingthe entire width of the structure. A reinforcing rod E isarranged centrally in the trough formed by each cross bar B, anda cementitious filling F is filled into the cavities formed by the angle iron cross bars B, the abutting flanges A A and the sides A and ends A ofthe units A, to embed the reinforcing rods D and E as well as the lugs A3 and ribs A", the top of the cementitious filling F being flush with the upper faces of the building light units A, as indicated in Fig. 2.

As shown in Figs. 1 and 2 one of the rows of units A is in the form of an open grate while the adjacent; row of units is of the closed type, that is, is provided with lenses G. The. open top unit A is provided with and 2. a

intersecting tapering bars A widerat the top than at the bottom so that the open spaces formed by the said tapering bars A the sides A and the ends A are gradually increasing in size from the top downward to the bottom of the unit to prevent dirt, rubbish or other extraneous matter from lodging in the said spaces thus rendering each unit practically self-cleaning. In using the structure as a grating on pavements extending over subways, cellars and the like, the open grate units insure proper ventilation of the area below the structure and atthe same time the open grate units are not liable to be clogged up by extraneous matter. Each lens G in the next row of units fits into the entirely open skeleton frame A andis supported at the bottom on an annular flange A formed integral with the sides A and the ends A of the frame A. Each of. the lenses G isfastened in place bythe use of cement, putty or similar material filled into the space between the edges of the lens G and the sides A and ends A ofthe units A, as plainly indicated to the left in Figs. 1

It is understood that by the arrangement described the lenses G refract the 'lightinto the space below the building light or grating and the rays of light can also pass directly through the open work units, which Y also form a ventilating means forthe space be low the construction as above'described.

I It is evident that a building light or a grating can be constructed using only building light units having lenses G or only units having open skeleton frames, and hence-I do not limit, myselfto either form of construction as the same is varied according to the use made of the construction.

As shown in Fig. 5, a grate I may be inserted instead of a lens Ur in the open top' of the unit, the grate I resting on the flange A The seats C of the side beams C may be entirely open, as shown in Fig. 8, so as to permit of placing the cross bars 13 into the seats from above, but the notches C? may be'provided at their upper end with converging shoulders C as shown in Fig. 7 so as to hold the cross bars B against upward movement, it being, however, understood that in this case the cross bars be slipped into the seats C endwise. The

are provided with seats corresponding to the crosssection of the channel iron cross beams. The channel iron cross bars form troughs ,..si1nilar to the troughs formed by the angle "iron crossibars for the reception of the cem- B in the manner described'and providing the units A with inclined sides and ends, it is evidentthat the rays of light can readily pass into the space below the construction to properly illuminate the same.

Having thus described my invention, I claim as newand desire. to secure by Letters Patent: Q
